Active clinical trials for "Sinusitis"

Asthma and chronic rhinosinusitis (CRS) are inflammatory diseases of the respiratory tract, asthma from the lower part, and CRS, from the upper part. In theory, these parts are correlated as if they are one single organ, namely "united airways", which means that if one is affected by any condition, the other might be impacted as well. However, this relationship has not yet been described down to the cellular and molecular levels. By investigating patients that have (1) asthma and CRS with nasal polyp, (2) asthma and CRS without nasal polyp, and (3) just CRS with nasal polyp, we aim to determine the correlation of the upper and lower part of the respiratory tract. At first, the characterization of disease will be determined by established clinical criteria, such as lung function, blood analysis for the presence of eosinophils (a type of white cells), and nasal polyp score. To continue, in-depth analysis of nose, oropharynx, and lung samples will help gain information about the inflammatory profile and local microbiome of the three different groups of patients through molecular and cellular assays. The results of this study will help to describe the hypothesis of the united airways which will provide better guidance for medical treatment of asthma and CRS with or without polyp, thus improving the life quality of patients.

Mycotic sinusitis is a rare inflammatory disease of the paranasal sinuses. In recent years, its occurrence is increasing. Due to this situation, mycotic sinusitis is gaining importance, even though most cases of mycotic sinusitis are limited on paranasal sinuses. Non-invasive forms of mycotic sinusitis are divided into mycetoma and allergic mycotic sinusitis. Mycetoma (fungus ball) usually affects only one paranasal sinus, most often maxillary sinus. The predisposing factors which participate on development of mycotic sinusitis are not exactly known. Some factors are considered as possible predisposing factors, for example deviation of nasal septum, dental treatment of upper jaw teeth or changes of nasal microbiome. The diagnosis of fungal sinusitis is problematic. With the increasing number of patients, it is essential to improve the diagnostic process. In present, suspicion of mycotic sinusitis is based on the patient's clinical symptoms and the endoscopic findings in the nasal cavity. Only in some cases nonspecific findings can be observed, such as smelly secretions from the nose, feeling of stuffy nose and pain over the affected sinus. Some patients may be completely asymptomatic, and only in some cases fungal masses can be observed in the nasal cavity. Computed tomography (CT) scans are gaining more and more importance. Typical sign of an affected sinus is obfuscation on CT scan but this sign is not specific for mycotic infection. Central hyperdense foci are also present in some patients, but they are also not specific and can imitate a foreign body. Identifying specific signs on CT scan could help with diagnosing mycotic sinusitis.

The goal of this study is to examine the mechanism of action of omalizumab in ex vivo tissue culture of whole human nasal polyps from patients with chronic rhino sinusitis with nasal polyposis (CRSwNP), such that specific molecular markers of inflammation can be identified.

The goal of this laboratory study is the examine the effect of mepolizumab drug on the health and function of the cells lining the human nasal airways in vitro cell culture derived from patients with chronic rhinosinusitis with nasal polyposis. The main questions the study aims to study are: To see what mepolizumab does to suppress inflammation of the human cells. To see what mepolizumab does to maintain barrier integrity of epithelial cells

The primary purpose of this pragmatic randomized clinical trial is to examine whether the addition of a phone-based multicomponent environmental intervention customized for Houston public housing residents with asthma will result in statistically significant improvements in key measures of health, quality of life, and resilience.

Primary Objective: To evaluate the efficacy of dupilumab as assessed by the reduction at Week 24 in sinus opacification on computerized tomography (CT) scan in the dupilumab group only Secondary Objectives: To evaluate the efficacy of dupilumab as assessed by the reduction at Week 24 in sinus opacification on CT scan and sinus total symptom score (sTSS) compared to placebo To evaluate the safety and tolerability of dupilumab in CRSsNP patients compared to placebo To evaluate the pharmacokinetics (PK) of dupilumab in CRSsNP patients compared to placebo Assessment of immunogenicity to dupilumab over time compared to placebo

This is a multi-center, randomized, double blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, PK, PD, immunogenicity and preliminary efficacy of CM326 in patients with chronic rhinosinusitis with nasal polyps.

There is a strong case for treating diseases of both the upper and lower airways (global airways) simultaneously because they share the same inflammatory mechanisms. About 9% have chronic sinusitis (CRS) and 4% of the Danish population are diagnosed with CRS with nasal polyps (CRSwNP)) and 7-10% have asthma. CRS has a multifactorial background, with CRSwNP characterized by Type 2 inflammation, and approximately 50% with Type 2 CRSwNP also have co-morbid asthma. Well-treated CRS has an impact on asthma control, and well-treated asthma has an impact on CRS. Several studies show that patients with asthma have low adherence, but only a few if any of studies are available on adherence in CRS. Aim: To investigate the effect of systematic and structured nursing supervision in patients with CRSwNP and asthma primarily on adherence. Hypothesis and research questions: Patients with respiratory diseases can improve their adherence to their non-medical and medical treatment for CRSwNP/CRS and asthma by systematic and structured nursing supervision compared to patients who receive usual care. In a randomized clinical trial, we will investigate whether the level of adherence measured by the questionnaire MARS-5-N and MARS-5- L in patients with CRSwNP and asthma can be improved by 7 points after systematic and structured nursing guidance at baseline visit and controlled after four months - compared with those patients who have not received the above guidance. Primary outcome: is change in adherence rate measured by the MARS-5-N/L questionnaire in patients with CRSwNP and asthma can be improved by 4 points after systematic and structured nursing guidance at the initial visit and controlled after four months - compared with patients who have not received the above guidance. Inclusion Criteria: Adherence to MARS- 5 L/N ≤35 at first visit, diagnosed with asthma (with/without allergic rhinitis) at initial visit, diagnosed with CRSwNP, able to use smartphone, ACQ ≥1.2 or ACT≤15 (partially uncontrolled asthma), >18 years of age, SNOT-22 score ≥35 Exclusion Criteria: Adherence to MARS-5- L/N >35 points at first visit,do not have smartphone, does not read/speak English, other illness requiring regular medication, pregnancy/pregnancy that started during the study, server psychological comorbidities Questionnaires: Patients must answer the following questionnaires at baseline and at 4 months follow up ESS, SNOT-22, ACQ-7, ACT, MiniAqLq, HADS, STARR-15

The study will be offered to patients for whom chronic maxillary sinusitis will be diagnosed in the first ENT (ear, nose and throat) consultation. These patients will then be seen in a stomatology consultation to determine whether or not a dental cause is objective
